I have a 2005 Passat TDI with Auto Trans that's only 2 months old.> It's been running fine till about 3 days ago. I noticed a pattern.> After work I'd drive it home or to a store nearby (20-30 minutes> highway driving), park the car and go inside for about an hour or 30> minutes. Once I get back into the car and drive again on local roads> around my town the problems start.>

It seems like the car will start shifting at much higher RPMs than> usual. I can't usually get it to shift at 3000 RPMs as I've seen it> recommended on other forums so it's usually shifting at around> 2500-2700.

I'd hate to think that a new car would act up already. Perhaps, my> driving needs to be adjusted since it's a diesel car.

Thanks in advance!>
